Greenhouse-Grown Olive Trees: Choosing the Right Pots


The magic of cultivating olives in a greenhouse! But before we embark on this leafy endeavor, let's talk pots – the olive trees' cozy abode.


The Potting Predicament


Selecting the perfect pot is like picking a stage for my trees to shine. Plastic, terracotta, or fabric? Each material brings its own vibe, durability, and, let's face it, charm! Think of my greenhouse as the VIP lounge and my olive trees as the superstars—needing their comfy spot in the limelight. After all, it's their show!

Sizing Matters


It's a Goldilocks situation, again! I want a pot that's not too snug and not too spacious. I'm aiming for a "just right" scenario that allows the roots of my olive trees to stretch without feeling like they've got too much legroom.

Draining Drama

Cue the crucial role of drainage! We all know olive trees enjoy a little hydration, but they're not big fans of soggy socks. Proper drainage holes are like the tree's personal umbrella on a rainy day—ensuring they don't drown in too much love.

Enter the Self-Watering Pot


Now, picture this: self-watering pots, the superheroes of the pot world! They'll be like having a personal butler for my olives. Regulating water, preventing overwatering (goodbye, root rot!), and even keeping the soil moist when I forget my daily olive tree chat.



When it comes to growing olives in my greenhouse, choosing pots isn't just about function; it's about finding the perfect stage for my leafy performers. And those self-watering pots? They're not just pots; they will be the master suite in my olive tree auditorium.


Olive Variety Show: A Hilarious Horticultural Lineup


When it comes to olive trees, it's like choosing characters for a garden sitcom!


Arbequina, the small but robust olive tree, embodies the charming sidekick stealing the spotlight with its fruity flavor. It prefers Mediterranean climates but showcases adaptability to various conditions with attentive care.


Kalamata, the iconic diva of Greek olives, leaves everyone else envious with its unmistakable taste. This olive variety thrives in classic Mediterranean climates. It revels in warm, dry summers and mild winters, showcasing its best performance when planted in well-drained soil and provided with the abundant sunlight it adores.


Picual, the sage among olive trees, presents an oil so versatile it’s akin to the Swiss army knife of olives. It prefers Mediterranean climates characterized by hot, dry summers and mild, wet winters. Its adaptability to diverse conditions makes it a valuable addition to any garden.


Meet the Frantoio, the Italian heartthrob of olive trees, thriving in the Mediterranean zone, charming with its bold and peppery oil, destined to steal the limelight.


Then there's the delicate Leccino, the romantic lead of Tuscan olive groves, suited for Mediterranean climates, wooing everyone with its mild, buttery essence, always ready for a starring role in culinary masterpieces.


Introducing the robust Pendolino, the dependable supporting actor from Tuscany, perfect for pollination in temperate climates, ensuring a fruitful ensemble cast with its reliable performance.


Let's not forget the hardy Mission, the resilient Californian starlet, adaptable to various climates, boasting a rich history and a flavor profile that's both fruity and complex, ready to make its mark in any setting.


Last but not least, the delicate yet flavorful Manzanilla, the Andalusian sweetheart thriving in warm climates, known for its mild taste and versatility, a definite scene-stealer in the olive orchard drama!


Some of these varieties are poised to turn my greenhouse into a captivating botanical theater of the absurd, each embodying its distinctive quirks and flavors.


Cultivating Olive Trees: Optimal Soil Mix


Crafting the ideal soil mix for the olive trees in my greenhouse will be a priority, ensuring they thrive in their limited space (read pots). While these trees are hardy, perfecting the soil composition will significantly boost their growth and productivity.


The Soil Blend Showdown


A potting soil, perlite, and compost trio, ready to give my olive trees the red-carpet treatment. Potting soil plays the steady base, perlite swoops in for the drainage party, and compost, well, it’s the nutrients' VIP! They blend like an Oscar-winning script, creating a soil mix that even the most discerning olive tree would give a standing ovation.


The Superstars

And then there’s peat moss, the moisture magician in this olive show, keeping those roots hydrated without any soggy drama. But hey, I’m eyeing the eco-warrior, coconut coir! It’s like peat moss’s cool cousin, offering moisture retention and root aeration - sustainably so! It’s the perfect green sidekick for my olive trees’ soil dreams.


Shortcut to Stardom


For those starting this soil mix journey, the red carpet might be a bit overwhelming. Fear not! Ready-made potting mixes tailored for Mediterranean plants or citrus trees are like the fast pass to olive soil heaven. They bring the right balance, saving you from soil mix chaos and ensuring your olives still get their dose of soil luxury.


Loose soil that drains like a pro, filled with nutrients fit for a royal olive feast. This soil mix sets the stage for my greenhouse-grown olives, proving that even in a limited space, my olives are destined for greatness!


Olive Oasis: Hydration Tactics for Thriving Trees


Implementing proper watering techniques is crucial for cultivating olive trees thriving in a greenhouse. So, here’s my hydration plan for the olive oasis within my greenhouse, ensuring the health and vitality of these remarkable trees.


Soil Checks


Picture this: I'm going to be the soil moisture guru. I’ll be like, "Hey soil, how you doing?" and check if it’s dry at the top inch. That’s my cue for when to water these guys, avoiding the whole soggy feet situation—nobody wants root rot, especially not my olives!


Directing the Flow


And when it comes to watering, I'll aim directly at the soil, not the tree leaves. It's like a leaf shower is a big no-no in the olive world. Deep watering sessions are on the cards too, encouraging those roots to go deeper and be strong like an olive tree should be.


Hi-Tech Assistants


But hey, I’m not doing this alone! I’ve got my eyes on these cool gadgets, self-watering thingies, and moisture meters. They’ll be like my olive tree hydration assistants, making sure my olives get just the right amount of water for their ultimate green spa experience.


Olive Trees in a Greenhouse: Light and Temperature Needs


Alright, so imagine my greenhouse as a sunbathing spot for some chic olive trees—basically, they’re my VIP guests demanding the best light in the house! These fellas thrive on at least six to eight hours of direct sunlight daily, so they're getting the prime real estate spots, soaking up that vitamin D like olive oil on a salad.


Temperature Prima Donnas


Now, here’s where it gets a bit tricky. These trees aren’t ones for temperature drama. I'm telling you, Goldilocks of the plant world—preferring it not too hot, not too cold, just right! During the day, they like to bask in a cozy 21°C to 29°C (70°F to 85°F), but come nighttime, they're more into a chillier 13°C to 18°C (55°F to 65°F ). I'm thinking of installing personalized climate controls just for them. You know, the "olive spa experience" to keep them feeling their best.


Olive Tree Climate Control


The challenge? Well, keeping these temperature divas content can be a task. But fear not! I'm going all-in with fancy ventilation systems—picture mini olive tree fans—and maybe some stylish coverings for the chilly nights. It's like playing the perfect tune for a demanding band—I mean, olive trees! Monitoring these temperatures is the key to keeping them happy, healthy, and ready to produce some of the finest olives this side of the greenhouse.


Mastering the Art of Olive Tree Haircuts


In the grand scheme of my greenhouse plans, olive tree pruning will be an art form! Picture me there, brandishing the shears with a determined look – not so much Michelangelo, more like Tree-chelangelo, sculpting these trees into the majestic beings they're destined to be.


The "Snip and Style" Approach


Picture this: olive trees sporting the latest foliage trends. I'll be trimming away dead or crowded branches, giving them a fresh, trendy look that screams "I'm ready for a garden party!" The aim? To sculpt these beauties for optimal growth, better air circulation (gotta let those leaves breathe!), and ultimately, to get them in the mood for some serious fruit production.




Olive Lovin': The Pollination Plot

In the world of olives, it's a bit like a solo dance party—these trees are self-pollinators! But hey, sometimes even these lone wolves need a little help from their friends. Learning the ins and outs of their unique pollination game can boost their fruit output.


Bumblebee Buddies


Enter my bumblebee posse! These fuzzy, flying superheroes are like the VIP guests in my greenhouse. They're going to be buzzing around, spreading pollen like confetti at an olive tree celebration. With their help, we're keeping the pollination party lively and productive!


Hand-Pollination Hustle


Now, if you don’t have bumble bees buzzing around in your greenhouse, don't sweat it! You can take matters into your own hands—literally! Think of it as playing Cupid for your trees, ensuring each olive gets its shot at stardom. It's like arranging a pollen-filled speed-dating event right there in your greenhouse!


In a nutshell, these olives might be solo stars, but a little help from bumbling bees will ensure a full harvest, keeping the greenhouse full of olive goodness!


Protecting My Olive Haven: Managing Pests and Diseases


Just between you and me (and perhaps a couple of olive trees), pests and diseases might try to crash this green party. But worry not, I've got a game plan to keep these uninvited guests at bay.


  • Pests Patrol: Let’s talk about these unwelcome critters, like the notorious olive fruit flies, itching to make a meal of my olives. These tiny troublemakers can wreak havoc, causing damage to the fruit. My strategy? I'm thinking of introducing natural enemies or traps, ensuring these pests don't get a free buffet at my olive feast. Vigilance is key; I’ll be on the lookout for signs of their arrival, ready to evict them!


  • Disease Defense: Now, let's address those sneaky diseases, like olive knot, trying to stir trouble among my green residents. It’s like they want to turn my olives into tiny knotted art pieces! But here’s the game-changer: regular pruning and sanitation to remove infected parts will be my first line of defense. And hey, prevention is better than a cure, right? So, I'm planning to maintain proper air circulation, ensure adequate sunlight, and keep an eye on the watering routine to prevent these olive woes from taking root.


  • Fungus Foibles: Powdery mildew, the uninvited guest that gives my olives a questionable dusty makeover, might try to crash the party. But fear not! I've got a few natural remedies up my sleeve. Sprays with baking soda or neem oil can show these fungal foes the exit door without causing harm to my olive darlings.


Remember, a vigilant eye, a touch of olive tree TLC, and a sprinkle of humor are my secret weapons in this battle against pests and diseases. My olive sanctuary will remain a healthy haven, resisting these unwanted guests!


Fertilizing Fiestas: Nourishment for My Olive Trees in Pots


Hold onto your hats, because in this olive garden party, we're talking fertilization! Imagine this as a food truck festival for my olives - they're hungry, but not hangry! Too much fertilizer and they'll be rolling out of their pots, but too little and they'll give me the side-eye.


But I've got this foolproof olive tree diet: I'll be feeding them sparingly but regularly during their growth spurt, usually from spring to early summer. Opting for a balanced, slow-release fertilizer specially crafted for fruit trees, ensuring they get all the nutrients without the sugar rush! It's quality over quantity, so think of it as serving them a gourmet meal without the food coma!


The Grand Finale: The Olive Harvest


It's harvest time in the olive kingdom. When the olives start showing off their luscious color and plumpness, it's game on! Let me grab my harvesting tools because these olives are ready for their grand exit from the trees. Time to pluck them before they pull an escape act!


Now, here's a little olive wisdom: aim for the sweet spot between underripe and overripe. Harvest when they're a gorgeous shade of green or even a dusky purple, usually from late September to early November. That's when the olive magic happens, and they're bursting with flavor. I can't wait to be able to gather those olives and get ready for the juiciest part – making my own olive oil!


And hey, if you've enjoyed this olive adventure, buckle up because I've got a whole garden full of stories waiting for you! Join me in exploring my unique concept of a city farm, unveiling the blueprint of this bustling urban oasis. Enter my unique dome greenhouse, a thriving hub for diverse plants and a serene tilapia pond. Inside, find a cozy modern tiny house, a sustainable retreat amid flourishing greenery. Stay tuned for the next post, where the journey through these fascinating ventures continues!
